My first introduction to genetics was in 10th grade Biology class. Mr. Berry, one of my all time favorite teachers, taught us more than we really needed to know about fruit flies. The only thing I clearly remember is they came either short winged or long winged, similar to short or long eye-lashed in humans I suppose.
Several vials of my fruit flies died. I don’t think I was really cut out to be a fruit fly farmer. But I did save enough for my results and report. What I did learn the most about was drawing the little chart to check genetic probability not only for fruit flies but for humans as well. It fascinates me.
So when I started having babies, thanks to Mr. Berry’s teachings, I knew the chances of hair and eye color and important things like the probability of them being able to roll their tongues. Jason and Travis look like Jim and Jill is definitely my daughter. And it’s beyond the boy/girl thing. Sometimes the way genes line up in a family, biological children look nothing like either parent. It’s like hidden recessive traits float to the top of the gene pool and suddenly surface.
When Jill was pregnant with Vivian in my mind she would have a little blonde who looked like her mom. To my surprise she has auburn hair and David’s navy blue eyes. I squint to see things clearer, but she still looks like her dad. When David is holding Viv it looks like David and mini David with a dress on.
God’s design for each of us is so precious. We can draw those little charts all we want, but the way the genes line up are His decision. Vivian is her daddy’s girl for sure. I’m only hoping she didn’t get his gene for size 14 feet.
